I don’t know where you live . . .
If you live in the US, I advise you to keep it simple
Use top-tier rated fuel. It has all the additives you could want, and you won’t get your hands messy dumping additional additives in the tank
If you’re a Costco member, start filling up there. Their fuel is top-tier rated
I can personally attest that top-tier fuel permanently took care of a fuel sending unit problem on one of our vehicles. Instantly, I might add
So if your car requires 87 octane . . . as many/most do . . . use top-tier rated fuel, at every fill-up you’ll get all those additives, and you won’t have to spend that additional money for mid- or premium-grade fuel
